Abstract

The invention relates to a concrete foaming agent and foamed concrete. The concrete foaming agent comprises the following components in parts by weight: 1-5 parts of hydrophobic rubber powder, 1-10 parts of gelatin, 5-15 parts of modified diatomite, 10-20 parts of water-absorbent resin, 5-10 parts of rosin resin, 5-15 parts of an anionic surfactant, 15-20 parts of a plant protein foaming agent and1-15 parts of cellulose. The foaming agent is used for foaming concrete, the frosting degree of the obtained foamed concrete is small, the foaming height of the foaming agent is high, and the foam stability is good.

Description

technical field [0001] The invention relates to the field of construction, in particular to a concrete foaming agent and foamed concrete. Background technique [0002] As a new type of energy-saving and environmentally friendly building material, foamed concrete has the properties of low density, light weight, heat preservation, sound insulation, and earthquake resistance, and is widely used in wall materials. In its preparation process, it is necessary to add a concrete foaming agent to make the concrete pore. Concrete foaming agents can be divided into three categories: chemical foaming agents, physical foaming agents and surfactants. In the process of foaming concrete, the current foaming agent is difficult to inhibit the frosting of concrete at low temperature. Therefore, it is very necessary to develop a foaming agent with good foaming property, high foam stability and inhibiting the frosting of concrete. SUMMARY OF THE INVENTION [0003] In order to solve the abov...
